More Interest

How do I help my husband become more interested in our sex? I've tried different positions. I've tried lengerie. I've tried just going for it and also taking it slower and doing more teasing and rubbing but none of it seems to interest him any more than anything else. As soon as he finishes he starts watching tv and stops paying attention to me. He won't touch me sexually and doesn't even try to make me finish. It seems like he doesn't care if I enjoy it and only cares if he finishes. It's been like this for so long that I can't even remember the last time I finished during sex. Any suggestions on how I can get him to care or be more interested?
